WITNESS ATTORNEY Patented Se t. 19, 193:3

UNITED STATES PATENT OFFICE This invention relates to painters striping devices and more particularly to compressed air spray devices of this character.

It is well known that what may be termed the hand striping process of painting is very unsatisfactory for many reasons, among which is that it is practically impossible to produce a stripe of uniform width and density, or which is parallel with another stripe or with a bead or the like even though the work is gone over repeatedly.

A primary object of this invention is to construct a striping device so.as to eliminate this tedious and expensive process of hand striping,

and to provide for the formation of a stripe uniform in width from start to finish and the width of which may be varied to meet the requirements of the work.

Another object is to so construct a device of this character that a novice may quickly learn its use and can stripe an automobile or other object in a very few minutes which if done by hand would require flve or six hours work by an ex ert painter.

Another object is to construct a device of this character that it may be easily assembled and disassembled for cleaning or other purposes.

In carrying out these objects, the invention is susceptible of a wide range of modification without departing from the spirit or sacrificing any of the advantages of the claimed invention; there being shown in the drawing for illustrative purposes a preferred and practical form, in which:

Figure 1 is a perspective view of a device constructed in accordance with this invention;

Fig. 2 is a side elevation partly in section showing the device in position for use;

Fig. 3 is a longitudinal section taken on the line 3-3 of Fig. 2;

Fig. 4 is a detail transverse section taken on the line -i4 of Fig. 2;

Fig. 5 is a detail section taken on the line 5-5 of Fig. 4;

Fig. 6 is a detail perspective view of the paint container used in connection with this device;

Fig. '7 is a plan view of a guide for use in striping wheel spokes; and

Fig. 8 is a similar view of another form of such guide.

In the embodiment illustrated this device which is designed to be moved over the goods to be striped and the paint or lacquer from which the stripe is to be formed is sprayed onto the object during the passage of the device.

This device is mounted on what may be termed a carriage composed of an axle 1 having two rubber tired wheels 2 and 3 adjustably mounted thereon and here shown secured in adjusted position by means of set screws 4. These wheels are adjustable to adapt the carriage to move over 90 and follow molding toes or ribs spaced different distances apart. Projecting laterally from the axle 1 and fixedly secured thereto is a clamp carrying bracket 5 at the outer end of which is mounted an air gun clamp 6. Projecting forwardly from this bracket 5 is an elbow-shaped arm '7 to the front end of which is secured a bar 8 extending laterally on opposite sides of said am 7 forming substantially a T head therefor. Mounted on this bar 8 for lateral adjustment toward and away from each other are two stripe regulating plates 9 and 10 constructed of any suitable material preferably of brass and which have upstanding lips 11 around their outer side edges and their front ends to prevent the paint or lacquer from passing off the plate at these points. The inner edges of the plates are made smooth and are designed to form between them the stripe regulating space through which the paint or lacquer is sprayed by means presently to be described. At the rear end of these plates 9 and 10 are thickened portions or bosses 12 which have bores extending therethrough shaped to fit the bar 8 on which the plates are designed to be slidably mounted and secured by means of set screws 13. It will be obvious that by adjusting .the plates toward or away from each otherand maintaining their edges in parallel planes and the space between them will be varied and consequently the width of the stripe painted therethrough will be correspondingly varied."

A spray gun 15 is removably mounted in the clamp 6 and comprises a body portion 16 tapered towards its front end as shown at 17 and provided at said front end with a flared discharge mouth or nozzle 18 preferably having an annular reinforcing rib 19 arranged at the base of said mouth. This body 16 has a bore or air passage 20 extending longitudinally therethrough and discharging into the flared mouth 18.

At the inner end of the body portion 16 and intersecting the bore 20 thereof is an air controlling valve 21 having a stem or plunger 22 arranged transversely of said body and provided at its outer end with an operating button 23 which is designed to be pressed inwardly against the tension of a coiled spring 24 to unseat the valve 21 when it is desired to permit the passage of air therethrough and through the passage 20. This coiled spring 24 abuts at one end against a movably threaded plug 25 located in the outer end of the valve sleeve 26 and which plug is adjustable to vary the tension of the spring. An air supply hose 27 is attached to the sleeve 26 as shown clearly in Fig. 1 and is designed to be connected with any suitable source of compressed air supply.

A paint supply nozzle 30 is mounted in a laterally projecting arm 31 of the body 16 of the spray gun and is adjustably and removably secured therein by means of a set screw 32. The discharge end of the nozzle 30 extends into the mouth 18 and discharges adjacent the outer end thereof as is shown clearly in Fig. 3, so that the discharge end of the paint nozzle is surrounded by the mouth of the air gun or spray gun and when the air is passing out through 'said mouth it will operate to suck out the paint from the nozzle and spray it through the space between the plates 9 and 10 onto the object to be striped.

The paint nozzle 30 is provided at its rear end with a flanged sleeve 33 designed to receive one end of an elbow shaped pipe 34 attached to and opening into a paint can or bucket 35. This paint can or container 35 is shown open although obviously it may be closed if desired. This can is removably mounted on the nozzle and may be replaced by another having paint of a different shade when desired to change the color of the stripe.

Mounted on the rear end, of the body 16 of the spray gun is a hand grip member 28 which may be of any desired configuration being here shown conforming in shape to the remainder of the gun and tapered towards its rear end. This grip 28 is shown threadedly connected with the body of the gun 16 by means of a reduced threaded extension 29 shown clearly in Figs. 2 and 3.

It will be obvious that in the use of this striping device the parts are positioned as shown in Fig. 2, the operator grasping the handle 28 and by depressing the button 23 with his thumb will open the passage 20 into communication with the air supply hose 2'! permitting the compressed air to rush through said passage out ofthe mouth 18 and suck out and spray the paint from the nozzle 30. The paint so sucked out by the compressed air is sprayed through the space between the plates 9 and 10 onto the object to be striped and the adjacent opposed edges of these plates control the width of the stripe so sprayed. It is, of course, to be understood that the carriage or the wheels 2 and 3 thereof are placed in guiding relation to some thick part of the object if such a thing is possible so that the wheel engaging with the molding or rib serves to guide the striper and insure its proper location in regard to such guiding rib or molding.

It is obvious that the spray gun 16 may be detached from the carriage by unclamping it .therefrom and used in any other place desired for spraying purposes.

While the striper is shown in position for use on the side of the car or other object to be striped it obviously may be used in vertical position on a flat surface and the paint container 35 may be removably held by any suitable means in the sleeve 33, a set screw 33a being here shown for this purpose.

To adapt the striper for use in striping wooden spokes of vehicles two forms have been devised shown respectively in Figs. 7 and 8 and numbered 40 and 50 respectively. These forms are made of thin sheet metal of any suitable type and are adapted to fit snugly over a spoke, plate 40 having a tapered opening 41 therein to provide for the making of a tapering stripe while plate 50 is provided with two slots or longitudinal openings 51 and 52 which converge at one end of the plate into a single slot 53 and which are designed for making right and left stripes on the spokes.

Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will, of course, be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of 'the invention or its scope as claimed.

I claim:

1. A striping device for paint and the like comprising a wheeled carriage for movement over the object to be striped, a stripe regulator fixed to the carriage and projecting forwardly thereof, a compressed air gun having the nozzle located in operative relation with the stripe regulator, and means for removably connecting the gun to the carriage so that said carriage and stripe regulator may be removed as a unit from the carriage and stripe regulator may be removed as a unit from the gun, the clamping means providing for adjustment of the gun towards or away from the stripe regulator.
